This European Standard shall be given the status of
28、 a national standard, either by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by April 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of p

The most relevant parts for racking ar
32、e EN 1993-1-1 and EN 1993-1-3. In order to have reliable state of the art guidance for those involved in designing these products and due to the differences in the shape of the structural components, detailing and connection types, additional technical information to the Eurocodes is required. The s
33、cope of CEN/TC 344 is to establish European Standards providing guidance for the specification, design, methods of installation, accuracy of build and also guidance for the user on the safe use of steel static storage systems. This, together with the need for harmonised design rules, was the reason
34、that the European Racking Federation (ERF) has taken the initiative for the CEN/TC 344. This TC is in the course of preparing a series of European Standards regarding Steel static storage systems as follows: prEN 15512, Steel static storage systems Adjustable pallet racking systems Principles for st
35、ructural design; prEN 15629, Steel static storage systems The specification of storage equipment; prEN 15635, Steel static storage systems The application and maintenance of storage equipment. The intention is for these EN series to be published sequentially over a period of ten years. Licensed Copy

37、 with floors. These tolerances, deformations and clearances are important in relation to the functional requirements and ensuring the proper interaction of the handling equipment used by personnel, trained and qualified as competent, in association with the specific type of racking system. The inter
38、action conditions are also important in determining the reliability of the storage system to ensure that the chance of an industrial truck impact, pallet impact or a system breakdown is acceptably low. The design safety philosophy given in prEN 15512 is based upon compliance with this standard. This
39、 European Standard gives guidance for a variety of issues including operating clearances, manufacturing, assembly and erection tolerance limitations, as well as deflection or strain deformation limitations under loads. This European Standard is limited to single deep adjustable beam pallet racking o
40、perated with industrial trucks or stacker cranes. Drive-in, double deep and satellite systems will be considered for inclusion in the document in the future. This European Standard specifically excludes the tolerances and deformation of the trucks and stacker cranes. It is the responsibility of the
41、truck or stacker crane supplier and the client or user to ensure that the tolerances, deformations and clearances, as quoted in this European Standard for the racking systems, are acceptable for the safe operation of the overall system. This European Standard gives guidance to be used in conjunction
42、 with the latest information from the truck and stacker crane suppliers regarding turning radii, tolerances and deformations of the truck and stacker cranes. 2 Normative references The following referenced documents are indispensable for the application of this document.
